Jose Altuve and Yordan Alvarez slugged first-inning home runs to key a four-homer assault that propelled the Houston Astros to a 4-1 victory over the visiting Texas Rangers on Saturday.

The Astros secured the three-game series and will aim for a sweep on Sunday in the finale. Houston prevented Rangers right-hander Jacob deGrom (3-3) from securing his 100th win by doing something only one other team has accomplished against deGrom in his illustrious career.

Altuve drilled a 2-0 fastball from deGrom 358 feet out to left field in the bottom of the first inning for his 42nd career leadoff home run. Altuve spotted the Astros a 1-0 lead with his fourth homer of the season and, two batters later, Alvarez doubled that margin by taking deGrom out to right.

Alvarez launched a 3-2 fastball 362 feet for his 15th home run this season. Suddenly trailing 2-0, deGrom rallied with strikeouts of Christian Walker and Braden Shewmake to begin a stretch where he retired eight of nine batters. Zach Dezenzo singled with two outs in the second inning.

But the Astros ambushed deGrom again in the fourth. Walker crushed the first pitch of that frame, a fastball, 422 feet to left-center field for his 11th home run and a 3-0 lead. After deGrom retired Shewmake and Brice Matthews, Zach Cole blasted his third homer 361 feet to right.

deGrom allowed four home runs for the second time in 257 career starts. On July 7, 2017, he surrendered four dingers in a 6-5 road win over the St. Louis Cardinals with the New York Mets. deGrom retired the final seven batters he faced following the Cole homer and surrendered four runs on five hits with four strikeouts in six innings. He matched his season high with 94 pitches.

Astros right-hander Kai-Wei Teng (2-3) worked five scoreless innings. He allowed two hits and issued four walks while notching seven strikeouts.

Joc Pederson produced an RBI single against Houston reliever Enyel De Los Santos in the top of the seventh, but the Rangers finished 1-for-10 with runners in scoring position and stranded 13 baserunners overall.

Altuve departed in the eighth, clutching his left side after grounding into a double play.
